Answer:
Density if iron shot = 7.92 g/ml (2 sig. figs.)
Explanation:
By definition, density is mass per unit volume. That is,
Density (D) = mass(m)/Volume(V)
mass(m) = 28.5g (given)
Volume(V, of iron shot) = 49.10ml - 45.5ml = 3.6ml
Substitutuing into D = m/V = 28.5g/3.6ml = 7.9166667 g/ml (calc.ans)
≅ 7.92 g/ml (2 sig. figs.)
Hope this helps. :-)
Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
The number of moles of Co that would be required to react with 6.14 moles of P4 would be 36.84 moles
<h3>Stoichiometric calculations</h3>
From the equation of the reaction:
6Co + P4 → 2Co3P2
For every 1 mole of P4, 6 moles of Co is required for complete reaction.
Thus, the mole of Co that would be needed for 6.14 moles of P4 would be:
6 x 6.14 = 36.84 moles

Answer:
The answer is true
Explanation:
This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move "uphill," from regions of lower to higher concentration. This process is called active transport, and requires some form of chemical energy.
